This invention relates to warning signs having a main lamp and anauxiliary lamp, and more particularly to such signs wherein a visualindication is given upon failure of the main lamp.

My invention is directed to a sign of the character stated of simple andinexpensive construction in which the lamps and associated parts aremounted in a novel manner such that a compact and convenient arrangementof parts results, the sign as a whole is relatively inexpensive, andready access is had to parts requiring replacement or adjustment.Further objects and advantages will appear from the detaileddescription.

Figure 1 is a front elevation of a warning sign of the type used toindicate a boulevard; Figure 2 is a rear elevation of this same sign;Figure 3 is a vertical sectional view of the sign; Figure 4 is asectional view along the line 44 of Figure 3; and Figure 5 is ahorizontal sectional view.

Auxiliary lamps have heretofore been provided in warning signs ofvarious types, and these auxiliary lamps have been arranged to take overthe functions of the main lamp upon failure thereof. Various means havebeen used to eiTect this result.

The apparatus disclosed herein, moreover, includes an indicator in theform of a third lamp, which indicator is lighted only when the main lampis burned out. This indicator lamp is positioned so that it illuminatesa small lens or bulls eye visible from the back of the warning sign, andthus a service man may ascertain the condition of the main lamp in thewarning sign through glancing at the back thereof. The sign is alsoprovided with a shield or partition of some sort between the indicatingmeans and the main or auxiliary source of illumination, so that theflashing of the main lamp will not i1- luminate the indicator lens.

In the particular embodiment of this invention illustrated herewith, awarning sign is shown having a shell or casing I! provided with a frontface or cover I This face may be hinged to the shell at the top thereof,as by hinges l2 and I3, and clamping means I4 and I5 are then providedto hold the face closed. The face has in the center thereof an openingH5 in which is positioned a lens l1, and above and below this openingare provided other openings in the shape of letters, as for example l8and I9. When the sign is illuminated, as by the main lamp 20, thecentral lens will flash a warning signal, and the words above and belowthis lens, as Stop Blvd, will be readily apparent;

The main lamp 20 is mounted upon a shelf 2|, and has mounted adjacentthereto an auxiliary lamp 22 Behind these two lamps, and separatedtherefrom by a shield or partition 23, is an indicator lamp 24 sosituated as to illuminate an indicator lens or bulls eye 25, which lensis positioned in the back of the sign. The lamps 20, 22 and 24 are allof common commercial design, and are mounted in threaded sockets 26, 21and 28 on the shelf 2|. The shield 23 may also be conveniently mountedon the shelf 2|,

as by the bracket member 29 and bolt 30. Im-

mediately below the shelf 2| is provided a box or container 3|, whichcontainer has therein appropriate circuit control means, and a socketmember is provided in one side of the container into which may beinserted the plug 34, which plug is attached to the extension cord 35leading from the source of electrical power used to illuminate the sign.

Should the main lamp 211 burn out the auxiliary lamp 22 will thereuponcontinue proper illumination of the face of the warning sign, while theindicator lamp 24 will furnish intermittent illumination t0 the lens 25,which illumination serves to call attention to the fact that the mainlamp has burned out and should be replaced, this being accomplished byappropriate circuit control means previously referred to.

What I regard as new, and desire to secure by Letters Patent, is:

1. In apparatus of the character described, a

. casing having a front closure member provided with openings for givingvisual indications, said casing having a rearward opening for giving avisual indication, a shelf within said casing, two lamps mounted uponsaid shelf, a third lamp mounted upon said shelf between and in rear ofsaid two lamps, a shield mounted upon said shelf between said two lampsand said third lamp and forming with said casing an enclosure for saidthird lamp efiective for excluding from said rearward opening light fromeither of said two lamps, a container supported by said shelftherebeneath and adapted to contain circuit control means for saidlamps.

2. In apparatus of the character described, a casing having a frontclosure member provided with openings for giving visual indications,said casing having a rearward opening for giving a visual indication, ashelf within said casing secured to the back wall thereof, two lampsmounted upon the forward portion of said shelf, a

said casing, a shelf within said casing and extending forward thereof,two lamps mounted upon the forward portion of said shelf, a third lampmounted upon the rearward portion of said shelf between said two lamps,and a shield mounted upon said shelf and forming therewith and with saidcasing an enclosure for said third lamp effective for excluding fromsaid second lens light from either of said two lamps.
